Description
Technical Field
The present invention relates to a measurement system and method for determining parameters of a multi-segment rod-like object.
Background
Various rod-shaped articles are produced in the tobacco industry, for example cigarettes with multi-segment suction nozzles, multi-segment filter rods. Segments of these objects are typically formed in a continuous process by cutting a continuous rod into individual segments or cutting a rod into small strips and then cutting the strips into individual segments. The production process requires the manufacture of a semi-finished product comprising a filling section and a tubular section, wherein the filling section may be filled with various fillers used in the tobacco industry, such as tobacco material, processed tobacco material, filter material or materials required to form a section of a specific nature, such as a section of the final product that does not filter but only allows flue gas to flow through and cool. The finished and semi-finished tobacco products may have tubular sections at the ends, i.e. hollow sections without filler, wherein the tubular sections may be thin-walled or thick-walled sections. From the point of view of the quality of these products and semi-finished products, it is important that the tubular end sections have a length that is narrower to the tolerance range, i.e. that they have the same length for the user of the product. There is currently no system that allows directly illuminating the front surfaces of segments of a multi-segment rod-like object, in which light scattering in the material of the segments would enable measurement of object parameters, including segment length. There is a need in the market for a measuring system that allows additional measurements to be made in addition to measuring the length of the tubular section.

The object of the present invention is a measuring system for measuring parameters of a multi-segment rod-shaped object comprising at least one filling segment and at least one tubular end segment. The measurement system includes: a conveying device for conveying a multi-stage rod-like object along a movement path transverse to an axis of the multi-stage rod-like object, wherein the conveying device is provided with a conveying trough; at least one light emitting device for generating a light beam for illuminating the front surface of the filling segment by passing through the interior of the tubular end segment; registering means for registering an image of the multi-segment rod object, wherein the registering means is configured to receive light of a light beam scattered by the material of the filling segment, which penetrates the material of the outer package of the multi-segment rod object and reaches the registering means to form a contour of the front surface of the filling segment in the image; and a processing unit configured to process the images of the multi-segment rod-like object registered by the registration means and to determine production process parameters and/or parameters of the multi-segment rod-like object.
The determined parameter may be the length of the tubular end section.
The determined parameter may be the length of the multi-segment rod-like object.
The determined parameter may be a distance between the front surface and the light emitting device.
The light beam may be directed to illuminate the edges of the tubular end section.
The determined parameter may be the quality of the edge of the multi-segment rod-like object.
The system may further comprise third lighting means for illuminating a side surface of the multi-segment rod-shaped object.
The determined parameter may be a position of the first filling segment.

The determined parameter may be a distance between the first front surface and the second front surface.
Another object of the invention is a method for determining parameters of a multi-segment rod-like object comprising at least one filling segment and at least one tubular end segment. The method comprises the following steps: conveying the multi-segment rod-like object in the vicinity of the light emitting device along a movement path transverse to the axis of the multi-segment rod-like object such that it is arranged to: wherein the light beam from the light emitting device directly illuminates the front surface of the filling segment when the filling segment is illuminated, wherein the light beam passes through the tubular end segment; registering an image of the multi-segment rod-like object, wherein the image is formed by receiving light of a light beam scattered by the filling segment material and passing through the outer packaging material forming a contour of a front surface of the filling segment on the image; and determining a production process parameter and/or a parameter of the multi-segment rod-like object based on the registered image of the multi-segment rod-like object.
The method may comprise the step of determining the length of the tubular end section and/or the length of the multi-section rod-like object.
The method may comprise the step of illuminating the edge of the tubular end section.
The method may comprise the step of illuminating a side surface of the multi-segment rod-shaped object.
The method may comprise the step of measuring parameters of a multi-segment rod-like object comprising two filling segments and two tubular end segments, wherein light scattered by a material of the first filling segment is registered to form a contour of a first front surface of the first filling segment and light scattered by a material of the second filling segment is registered to form a contour of a second front surface of the second filling segment.
The solution according to the invention allows accurate measurement of the product and of the semi-finished product, with emphasis in particular on the end segments. The high measurement accuracy is due to the fact that the high intensity beam of non-scattered light directly irradiates the front surface of the inner filling section and that there is only information on the light transmitting section scattered by the material passing through the section and its position. In particular, geometrical parameters such as the length of the tubular segment, the length of the rod-like object, and furthermore the quality of the edges, such as the breaking of the end edges, and also the position of the inner segment can be verified. It is suitable for inspecting various types of products whose end sections are hollow.

Detailed Description
The present invention relates to determining parameters of a multi-segment rod-like object comprising at least two segments, which will be referred to herein as multi-segment rod-like object. The multi-segment rod-shaped object 1 shown in fig. 1 is a five-segment object comprising a first end segment 2, a first inner segment 3, a second end segment 4, a second inner segment 5 and an intermediate segment 6. The first end section 2 has the form of a tube, which is a first tubular end section 2, and the second end section 4 also has the form of a tube, which is a second tubular end section 4. The first tubular end section 2 and the second tubular end section 4 may be made of paper or cardboard. The thickness of the multi-segment rod-shaped object 1 shown in fig. 1 is greater than in the other embodiments. Furthermore, it may be a thick-walled tube made of a filter material or other material. The tubular section is open on both sides, wherein the finished rod-like object does not contain any structural or filling elements within the tubular section, so that the light beam can pass through the interior of the tubular section without obstruction. The thick-walled tubular segment may have a circular, square, triangular opening or it may have any other pattern of cross-sectional shapes.
The first inner section 3 is a filling section, and similarly the second inner section 5 is also a filling section. The filling segments 3,5 are in the form of cylinders comprising filler used in the tobacco industry. The filler may be a filter material, a tobacco cut filler material, a processed tobacco material, a material having an aromatic substance, or the like. Materials used in the tobacco industry are generally transparent to electromagnetic radiation in the visible and invisible ranges. The fibers of the filter material are positioned such that the fibers are connected at a plurality of points to form a spatially permeable structure, light of a light beam incident on the structure being scattered in different directions. In the following description, a beam of electromagnetic radiation will also be referred to as a beam for simplicity. In the present example of a five-segment rod-shaped object 1, the intermediate segment 6 has the form of a tube, wherein the intermediate segment 6 may be formed of any material and may be filled. The segments of the multi-segment rod-shaped object 1 are typically wrapped in an outer wrapper 7, such as tissue, over the entire length of the object. The filling segments 3 and 5 may have their own outer packaging material. The segments may be formed in a continuous process by cutting the continuous rod into individual segments or cutting the continuous rod into small strips and then into individual segments, which may be filled in a discontinuous process. The thickness of the outer wrapper is not shown.
The present five-segment rod-like object 1 is an object that is symmetrical with respect to a plane S perpendicular to the axis n of the five-segment rod-like object 1. The object may be divided along the plane S into two identical multi-segment rod-shaped objects having a length equal to half the length of the five-segment rod-shaped object 1. The resulting multi-segment rod-like object comprises a tubular end segment 2 or 4, a filling segment 3 or 5 and half of an intermediate segment 6.
Fig. 2 shows a three-segment rod-shaped object 1' comprising a first end segment 2, a filling segment 3 and a second end segment 4. The first end section 2 is in the form of a tube, which is a first tubular end section 2, and the second end section 4 is also in the form of a tube, which is a second tubular end section 4. As with the object of fig. 1, the first tubular end section 2 and the second tubular end section 4 may be made of any material and may have any wall thickness. The three-segment rod-like object 1' is also an object symmetrical with respect to a plane S perpendicular to the axis n of the object.
Fig. 3 shows a three-segment rod-like object 1", which is in the form of a cigarette and comprises a first tubular end segment 2 and two filling segments: a filling segment 3 comprising filler and a segment 15 comprising shredded tobacco.
The measuring system 10 shown in the embodiment of fig. 4 comprises a conveying device 11, a first light emitting device 12, a second light emitting device 13 and a registration device 14 for capturing images. The conveying means 11 may be in the form of a drum conveyor 8 provided with a conveying trough 9 adapted to receive and transport the multi-segment rod-shaped objects 1 (alternatively, the conveying means may be in the form of a belt conveyor provided with a trough for the multi-segment rod-shaped objects). The drum conveyor 8 has an axis of rotation k and rotates in the direction indicated by the arrow. The conveying trough 9 is in the form of a cylindrical trough having an axis m, and the multi-segment rod-shaped object 1 having a longitudinal axis n is placed in the conveying trough 9 such that the axis n of the multi-segment rod-shaped object 1 substantially coincides with the axis m of the conveying trough 9. In fig. 5, the measuring system 10 is also shown, in which a section through the drum conveyor 8 (the rotation axis k lying in the plane of the section) is visible and the multi-segment rod-shaped object 1 shown in fig. 1 is in the measuring position M. The first light emitting means 12 generates a first light beam 18 having an axis u, wherein the axis u is arranged parallel to the axis n of the multi-segment rod-shaped object 1, furthermore, the axis n and the axis u may substantially coincide when the multi-segment rod-shaped object 1 is in its measuring position M illuminated by the first light emitting means 12. The second light emitting means 13 generates a second light beam 19 having an axis v which is positioned parallel to the axis n of the multi-segmented rod-like object 1, furthermore, the axis n and the axis v may substantially coincide when the multi-segmented rod-like object 1 is in its measuring position M illuminated by the second light emitting means 13. A registration device 14 for registering the images is located above the measurement location M. The first light emitting device 12 and the second light emitting device 13 may be positioned such that the axis u of the first light beam 18 from the first light emitting device and the axis v of the second light beam 19 from the second light emitting device coincide. The registration device 14 may be in the form of a camera and may comprise a plurality of image registration devices.
At the measurement position M, the first light beam 18 from the first light emitting device 12 passes through the interior of the first tubular end section 2 and illuminates the first filling section 3. The light passing through the first tubular end section 2 is scattered by the material of the first filling section 3 and partly passes through the outer packaging material 7, wherein a part of the scattered light beam reaching the registration means 14 is marked 20. The second light beam 19 from the second light emitting device 13 passes through the interior of the second tubular end section 4 and illuminates the second filling section 5. The light passing through the first tubular end section 2 is scattered and partly passes through the outer packaging material 7, a part of the scattered light beam reaching the registration means 14 being marked 21. The first light beam 18 passes centrally through the first tubular end section 2 and the second light beam 19 passes centrally through the second tubular end section 4, wherein the filling section can be illuminated non-centrally, possibly at a slight angle. After passing through the tubular end sections 2,4, neither the first beam 18 nor the second beam 19 is scattered and maintains its own intensity.
The registration device 14 receives the ambient light reflected from the side surface 1A of the multi-stage rod-like object and the scattered light from the light emitting devices 12 and 13. Fig. 1a shows a registered image P of a multi-segment rod-like object 1. The image P shows an exemplary contour of a multi-segment rod-shaped object 1, wherein the bold lines represent edges and surfaces of segments, wherein 2A is the edge of the first tubular end segment 2, 3A is the front surface of the first filling segment 3, 4A is the edge of the second tubular end segment 4, 5A is the front surface of the second filling segment 5. The position of the first front surface 3A of the first filling segment 3 is defined as the boundary of the scattering region 3B where the first light beam 18 is scattered by the material of the first filling segment 3. The position of the second front surface 5A of the second filling segment 5 is defined as the boundary of the scattering region 5B where the second light beam 19 is scattered by the material of the second filling segment 5. The image P is processed in the processing unit 22. The processing unit 22 is configured to determine parameters of the multi-segment rod-like object 1, such as a length a of the first tubular end segment 2 measured as a distance between the edge 2A of the first tubular end segment 2 and the front surface 3A of the first filling segment 3, a length b of the second tubular end segment 4 measured as a distance between the edge 4A of the second tubular end segment 4 and the front surface 5A of the second filling segment 5, a length c of the multi-segment rod-like object 1 measured as a distance between the edges 2A and 4A, and a distance d between the front surfaces 3A and 5A. The processing unit 22 is configured to detect the positions of the first filling section 3 and the second filling section 5, a defective position defined as a line corresponding to the front surface 3A of the first filling section 3 at a position other than perpendicular to the axis n of the multi-stage rod-shaped object 1, a defective position defined as a line corresponding to the surface 5A at a position other than perpendicular to the longitudinal axis n of the multi-stage rod-shaped object 1. The determined information on the parameters of the rod-shaped object 1 is sent to the control unit 23, and the control unit 23 may send a signal for rejecting defective multi-segment rod-shaped objects 1. The image quality (contrast enhancement, image brightness) can be improved by using further light emitting means in the form of light sources 24, 25 illuminating the side surfaces 1A of the multi-segment rod-shaped object 1. Cameras provided with lamps arranged around the camera lens for illuminating the field of view of the camera are known.
An example of a production process parameter is the distance e between the front surface 3A of the first filling segment 3 and the first lighting means 12. Since the first light emitting means is in a fixed position, a change in the distance e may represent an incorrect position of the multi-segment rod-shaped object 1 in the conveying trough 9 in the axial direction along the axis m.
In the embodiment shown in fig. 5 and in the embodiment of fig. 6 discussed below, the symmetrical semi-finished product is represented in the form of a rod-shaped object with tubular end sections 2 and 4 at both ends. The measuring system 10 according to the invention may be configured for a multi-segment asymmetric rod-shaped object with a tubular segment at one end. For example, the measuring system 10 may be equipped with a lighting device, for example as shown in fig. 3, in the case where the product for taking the parameter measurements is a cigarette provided with a mouthpiece having a tubular section at its end.
Fig. 1b shows an image P ' of a defective multi-segment rod-like object with a broken line representing the first edge 2A ', indicating that the first edge of the first tubular end segment 2 is deformed and that the light scattered by the second filling segment 5 forms a line corresponding to the front surface 5A ' positioned without a line perpendicular to the axis n of the multi-segment rod-like object 1, indicating that the second filling segment 5 is deformed or positioned defectively, e.g. that the filling segment 5 is rotated when using a filling segment with a length close to the segment diameter.
The image P "for a three-segment rod-like object shown in fig. 2 is similar to the image P for a five-segment rod-like object shown in fig. 1. The scattering regions 3B, 5B, 3D registered in the image may vary depending on the type of material of the filling segments 3,5 and the wall thickness of the tubular end segments 2, 4. Fig. 3a shows an exemplary image P '"for a multi-segment rod-shaped object 1' in the form of a cigarette.
Fig. 6 shows a second embodiment of the measuring system 10' in which the first light beam 18 partly passes through the first tubular end section 2 and illuminates the first filling section 3, as well as the first edge 2A of the first tubular end section 2. Light incident on the first edge 2A is scattered and reaches the registration device 14 as a light beam 26. The second light beam 19 partly passes through the second tubular end section 4 and illuminates the second filling section 5 and also illuminates the second edge 4A of the second tubular end section 4. Light incident on the second edge 4A is scattered and reaches the registration device 14 as a light beam 27. The image P of the multi-segment rod-shaped object 1 is formed in particular by light reflected and partly scattered by the first edge 2A and the second edge 4A and by light scattered by the first filling segment 3 and the second filling segment 5.
The present invention relates to a multi-sectional rod-shaped object having two ends in the form of tubular segments, and to a multi-sectional rod-shaped object such as a cigarette, of which only one end is a tubular segment, the end of the mouthpiece of which is provided with a paper or cardboard tube, possibly a thick-walled tube made of cellulose acetate for example.
